Celebrities are joining the opposition to an animal abuse bill in Tennessee that is waiting for the governor's signature. Nashville singer Emmylou Harris penned a letter to Tennessee Gov. Bill Haslam on Friday asking him to veto the bill that would require anyone recording or taking photos of livestock abuse to turn images over to law enforcement within 48 hours. Harris wrote that the bill would "paralyze the efforts of those concerned about the treatment of animals to collect evidence of a pattern of routine cruelty." Ellen DeGeneres also posted a video on her website on Wednesday of an interview with Wayne Pacelle, president of the Humane Society of the United States, which has launched TV ads about the bill.
